More than one correct expression
Different expressions can select the same shaded regions. The key provides a valid expression and useful equivalents where available. A learner can justify another answer by checking every atomic region against it.
Choose a focused set of options while learning the notation. The preview and downloadable PDF contain the same questions, with the answer key kept separate from the student pages.
Learning objective
What this activity builds
Describe a shaded result with a valid set expression and explain equivalent names.
Worked example
Only the part of A outside B is shaded. Give two names for it.
A ∖ B and A ∩ B′.
Both expressions require membership in A and exclude membership in B. Compare the selected regions, not the spelling.
Teaching notes
Make the practice count
- Describe the shading in words before using symbols.
- Check every region against the proposed expression.
- Accept equivalent expressions with the same result.
- Separate an equivalent answer from an expression that only partly matches.
